Specification of Letters Patent. Patented July 12, flghfi.

Application filed. November 4, 1908. Serial No. 461,008.

To all whomit may concern:

Be it known that I, GUsrAvn ,DEBLADIS, a citizen of the Republic ofFrance, and resident of 3 Rue Cail, Paris, France, have invented certainnew and useful Improvements in Cushion-Tires, of which the following isa specification.

This invention relates to 'an'improvement in cushion tires and has forone of its objects to provide a devicefof this character,

wherein the resilient material simply acts as a cushioning device forthe. wheel and not as the tire tread.

Heretofore, cushion tires have been invented, which provide for the-useof elastic or resilient tires, these tires being covered by a metallicshoe. One of the disadvantages of this construction is, however, thatmetallic shoes as a general rule simply have vertical movement and donot provide for any lateral'movement of the metallic shoe-.-

The present invention overcomes this ob jec tionable feature byproviding a plurality of'shoes which are so connected that they permitof lateral, vertical or oblique movement of the shoes to conform withthe deformations of the resilient or elastic member. Further objects andadvantages of the present'invention will appear from the followingdescription with referenceto the ac- Ycompanymg drawing, wherein,

Figure 1 is a side. elevation of a portion of a wheel embodying myinvention, part 1 thereof being shown in section, ig; 2Jis a sectionalview of Fig. 1, Fig. 3 illustrates a detail vertical section of amodified form,

Fig.4 isa cross sectional view taken onthe line 4.1- Fig. 3, Fig. 5' isa View, part ofwhich is anend elevation 'and'part a section disclosing aconstruction wherein a plurality of tires are secured to the wheeltelly, Figsrfl and 7 "are .detail perspective viewsof the opposite endsof one of the metallic shoes, Fig. Sis a perspective view of the movablesupporting guide, and Fig. 9 illustrates a modified form of myinvention.

' Referring more'specificallyto the draw-. ings, wherein like lettersofreference indi-' vcate like parts throughout the difl'erent views, adesignates an inner rim, which is provided with the usual spokes a. Se-

In assembling the parts thus far described,

the shoes 0 are placed upon the resilient members b sothat the flangeportion e of each shoe will receive the enlarged head portion 01 of theadjacent shoe, each of these partsv being provided with a suitablebearin through which passes the. retaining bolt f, Which continuesthrough an aperture formed in the rim ()5 and secured to a concentricring .a by any suitable means. It will be seen that the bearings formedin the flanged portion 6 and the enlarged portion d of the metallic shoeand also the apertures in the I rim a are slightly larger than thediameter of the rod f, whereby the said rod is permit ted a limitedamount of play.

' It will be understood that the flanged portion 6 of one shoe entersbetween the two upright flanges-j 011 the enlarged head portion of theadj acentshoe, being retained in place by means of the rod f and alsothe rods is. In order to increase the surface of contact between therods k and theflanged'portion e, a movable supporting guide 122, whichispivotally secured to one of the rods k, may be employed, said guidebeing adapted tofollow the positions of the, flanged portion 6. The headportion (2 of. the. metallic shoes, is provided with a socket'formation, wherein the enlargedsemi-spherical head of the rod fisadapted to fit, forming a substantially,

universal oint, while the opposite or flanged end, e of the adjacentmetallic shoe has a bearing surface on the inner face of the enlargedhead portion (1, thus allowing the three elements, z'. e. the headportion (Z of one sho -the flanged portion 6 of the adjacent shoe andthe rod f, to have relative independentmovement.

' As has heretofore been stated, the head portion (1 is provided with apair of parallel flanges 7' extending longitudinally of the shoe, andbetween which flanged member 6 is adapted to fit, while a pair oftransverse bars or rods [c extend between the two flanges and preventthe displacement of the member e.

' These rods 70, are very importantinasmuch as they hold the twoadjacent shoes Irom displacement but at the same time permit relativemovement between the two.

The rods f may be arranged in a variety 1' of ways, as shown in Fig. 1where the converging ends are secured to aring arranged concentric tothe hub of the wheel or as shown in Fig. 3. In this instance, t econcentric ring is dispensed with and the rods project but a shortdistance beyond the inner rima where they terminate with a screwthreaded end portion. A suitable elastic block 2' is placed about theinner end of the rod and receives a bearing head i which bears againstthe recessed face of the block a. This bearing head is held in place bymeans of nuts Z adjusted on the screw threaded ends of the rods f.Interposed between the bearin block '5 and the nuts I are the flangecasings n and 0, having the tension spring 7 so placed between them thatthe casing 41. is forced against the bearing block 2' while the casing 0is forced in against:

the nut Z, which consequently serves to hold the rod f in correctposition. The function of this spring 1' is simply to prevent the.rattling of the different parts as the shoes are I displaced by contactwith the road bed and at the same time to assist in holding thedifferent parts in their applied positions.

Referrin now to Fig. 5 a construction is disclosedw ich is adapted to beused with heavy vehicles, and where a plurality of small tires arrangedin series are preferable to one large one. Substantially the onlydifference embodied in this construction over that of Fig. 1 is that theconcentric ring a which is adapted'to receive the converging ends of thetension bolts 7 is. composed of a number of separable parts securedtogether by fastening means of suitable character.

In Fig. 9 another arrangement of the guidng plate or block m is shownbeing carried by a spherical shapedmember, WhlCll 1n turn is madeintegral with a nut Z", this nut Z screwing on to threads formeddirectlyon the rod ff, thus holding the guide 1n pro) imi'ty to theflangedportion eof the metall c shoe but permitting the shoe to followthe compression or deformation of the resilient segment. I

To prevent the accumulation of dust,.dirt

and other foreign elements and to provide for some means whereby thejoints formed by the junction of the adjacent shoes and the rods 7', maybe lubricated, the socket formation of the head portion (Z is adapted toreceive the cover p, thus permitting any suitable lubricant to be placedin the socket and the cover 71 adjusted.

From the above description, it will be seen that any deformation of theelastic segment which may occureither because of the weight of the loador because of obstructions in the road, will be readily followed by themetallic shoes.

Having thus described my invention, what I'claim as new therein anddesire to secure by Letters Patent is v 1. In a resilient tire, aplurality of metallic shoes, each of said shoes comprising an enlargedhead portion, provided with a socket formation, a stay bolt, having anenlarged semi-spherical end, which is adapted to fit in the socketformation, whereby said stay bolt and metallic shoe have independentrelative universal movement.

2. In a resilient tire, the combination with a wheel rim, of apluralityof metallic shoes secured about said rim provided at their0pposite ends with an enlarged head, the inner face thereof presenting acurved surface,

and a' flanged portion respectively, the flanged portion of one shoeconstructed to.

bear against the curved surface of the enlarged head of the adjacentshoe, and inde pendent means flexibly connecting the adjacent shoes,whereby said shoes and means are capable of relative universal movement.

3. In a resilient tire, a plurality'of metallic shoes, each of saidshoes comprising a hollow semi-spherical head portion and a flanged endportion, the flanged end portion of one shoe constructed to bear againstthe curved surface of the head portion of the 'adj acent shoe, meanspositioned within said head portion for connecting the co-adjacentshoes, and a guide block pivotally carried by the head portion fornormally holding the flanged end portion of one shoe in fc'ontact treadsurface thereof, of independent means shoes.
